Don't know if the developers can use this to make their rom stable but... only wanted to share this news:
Sony will release their JellyBean code from AOSP experiment to GitHub
Just a heads up, developer Rayman has a Sneak preview photo of 4.4 kitkat on Xperia S
btw, just something that i am always curious. If sony cant get 4.2, 4.3 4.4 to work, why do other developer managed to get it work?
Well i am no expert but this is my take, as some people are stating Qualcomm isn't releasing any more drivers so...
AOSP experiment status:
Submitted a request for Runstatic to add that feature to Sony Smartwatch.
Very annoying to have to turn the device always on, and with an app that Sony brings with the watch support should be better.
Anyway installed your options until/if Runtas...
